Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples, but be not intended as to the present invention limit according to
According to.
Embodiment: a kind of method that pipeline tapping blocks, as shown in figures 1 to 6: including the following steps:
A, the preparation stage: the material of preparation includes adapter tube 3, hole making drill, sealing plate 4 and fixing piece；
Adapter tube 3 therein, sealing plate 4 are that resistant material is made, and hole making drill directly uses existing hole driller with pressure；
In the present embodiment, the cross section of the sealing plate 4 is oblong structure, the radian of the sealing plate 4 and the inner wall of original pipeline
Curvature is consistent, and the upper surface of the sealing plate 4 is opened up there are two circular hole, the two sides circle on the center of circle and oblong structure of the circular hole
The heart is overlapped, and the diameter of the circular hole is 26mm, depth 4mm, is fixedly installed with nut (D in Fig. 5 at) in the circular hole, tool
Body is referring to shown in Fig. 4 and Fig. 5.
B, the production of adapter tube 3: the outer rim of adapter tube 3 is equipped with helicitic texture, each inside cutting 2mm in the middle section two sides of adapter tube 3, tool
For body as shown in figure 3,3 bottom of adapter tube is fixedly connected with tube socket 31, the bottom outer-edge of tube socket 31 deflects away from 3 outer wall 5mm of adapter tube or more,
The part deflected away from is sealed with original pipeline and docks, and the upper surface of tube socket 31 is embedded with sealing ring, is boxing at the B in Fig. 3
Seam；
The thickness of the tube socket 31 is between 3mm-10mm, the radian and original of the tube socket 31
There is the curvature of inner wall of the pipe consistent, improve the fitness of docking, to improve leakproofness.
C, the production of sealing plate 4: for the sealing plate 4 in this implementation with a thickness of 9mm, the upper surface of sealing plate 4 mills out a circle sealing surface (figure
At C in 4), enclose in the middle part of sealing surface and set out a boss 41, be embedded on sealing surface sealing ring (at the E in Fig. 6, this implementation
O-ring structure is used in example), the boss 41 is higher than sealing surface 4mm, the lubrication groove of the outer profile of the boss 41 compared with hand hole 1
Exterior feature has been offset inward the distance of 1mm, specific as shown in Figure 6；
D, it aperture: needs the position of aperture extension tube attached 3 to drill out on original pipeline using pipeline perforator and connects hole 2, connect the cross in hole 2
Section is circular configuration, connects the diameter in hole 2 depending on the diameter of adapter tube 3；
Then a hand hole 1 is drilled through in the another location of original pipeline, the cross section of hand hole 1 is oval structure, a diameter of
150mm；It is specific as shown in Figure 1.
At a distance from the center for connecing hole 2 between 200mm-400mm, the distance is convenient to be grasped manually at the center of the hand hole 1
Make.
E, the installation of adapter tube 3: 3 be will take over first and put pipeline into from hand hole 1, then gone out from inside to outside from primary tube trace interpolation
Hole 2 is connect, outside will take over 3 with clamp nut and be fixed on original pipeline；
F, the closure of hand hole 1: it will become a full member after in 4 oblique cutting entry hole 1 of sealing plate, finally make sealing plate 4 and original pipeline using fixing piece
It is kept fixed.
The fixing piece includes the bracket 5 that at least two horizontal spans are greater than 1 width of hand hole, is worn in the middle part of the bracket 5
Equipped with stud, one end of the stud is connect with the nut thread on sealing plate 4, and the other end of the stud connects
It is connected to the second clamp nut, as shown in Figure 6.It is tight come the installation for adjusting sealing plate 4 by the second clamp nut of rotation when actual installation
Close property.
Structure after completing installation and blocking is specifically as shown in Figure 2.
It is worth mentioning that:
In opening step D, due to being to carry out tap operation on rubber lined pipe, in actual operation in order to prevent in inner wall of the pipe
Line with rubber there is a situation where tear, it is necessary to the feed velocity of strict control hole making drill avoids suddenly hitting.In addition, when fixed
After position drills through, it should the time for stopping 4-5 seconds slightly, be further continued for carrying out, if not stopping direct drilling, internal line with rubber has
Fold may occur, not only influence drilling effect, but also increase the risk of line with rubber tearing.
In 3 installation steps E of adapter tube, in order to accelerate the speed of clamp nut sinking, installation effectiveness is improved, so will take over 3
Mid-section threads inwardly cut 2mm, after the installation that clamp nut completes butt tube 3, installation is outer on the top of adapter tube 3 adds
Valve, and connect with another pipeline docked is needed.
Hand hole 1 blocks in step F, and when practical operation, the bore of hand hole 1 is larger, it is contemplated that sealing plate 4 install after with primary tube
Line with rubber squeezes inside road, and under the action of itself stress, fold, which occurs, for line with rubber influences leakproofness, so selecting O on sealing surface
Shape circle is sealed, and the width of O-ring selects 5-6mm.
After the completion of adapter tube, pressurization test is carried out.
In April, 2019, in Hangzhou, Shan Sen mechanical equipment Manufacturing Co., Ltd carries out applied voltage test, when suppressing to 1MPa
When, leakage is not generated, is occurred without obvious corrosion condition yet, production needs are complied fully with.
